B it known thatgI, JAco Davm WQLF, a citizen ofv the United States of Amer-lea,

residingat 17 'Ihrogmort'on avenue, inthe-A city `of` London, England, have invented certain Anew anduseful Improvementsm Ore-ConcentratingApparatus, 'of which the following isa specification.

concentrating apparatus. v

In, all 'cases separation A,and .concentration are effected witha V minimum amount of wash waterandthe Au1 mayfbe` warmedor h cati"4 4j 'fltlias' 'alread been proposed byf me and qthersto em l'oy in a wet concentration@ process jan en less traveling belt coated with .at-' grease, viscous oil, or thelike, and impart a shaking, motion tosaidbelt, but allsuch apparatus' have not "hitherto'beenentirely commercially successful,v principally owing tothe difficultyaud expense experienced in separating the metal yor valua le'portions from .the-grease or oil employed; lly'means either-present invention thes'ejdiiic ties' are l os'sl-4 'not o fy entirely overcomebut it is i blel to treat slim'es .not capable. of: .lng treated'in any'other way, and moreover cered without prejudicially aiecting the operation. ,The present inventionv comprises essen! tially, a belt prepared in `the-manner here lin'aiter specified, wherebythe metal or valuable portion is not coated 'or minedl with the -oil yet-in conj'unctionawith the special `belt-shaking 'apparatus employedan entire separationfrom the gangue is easily effeeted. v

A'In the accompanying drawing, i x Figure 1 is a view in side 'levation of an apparatus' constructed according to the present invention, Y

Fig. 2 is a view in plan thereof, and Fig. 3` is an end view thereof. Throughout the views similar parts are marked with like letters of reference.

The apparatus comprises'essentially a table a-which may or may not be laterall inclined-adjustably carried on a suitsaid table arranged to allow for longitudionn-conomxrermonrrmrus;

The usual means4 employed in separating apparatus of 'the travelmg belt type are fusting the, eccentric and rag-link gear, for feeding thel pulp and washl water on tothe (provided for adfbelt and for removingv thel concentrates from 1 'the belt.

The main shaft Z driven 'b means of `a pulley Z1 is mounted'in sitab e bearings on the frame b andA is connected at one en dto the dragflink gear .d'theflateralfinotion o fj which is ,transmitted to the table; through a rod-"721. `On theother end fof said shaftis a bevel wheel l? drivinga similar wheel m bearings'on the iframe and arranged at vthe feed4 end of the apparatus. The belt die. f driven from the "roller e1 by means of'a belt pulley e?. The .shaft/m1, carries the adjustable ecntric gearsl h both of which' are adjustable by means. of a hand wheel h carried by a bracket .on the frame.- :This hand wheel carries la sleeve provided internally with azright and. left hand thread adapted to engage corresponding threads on4 the ends of a divided rod ha, the 'free ends of which p are connected to rocking levers for adjust- .ing the throw of theeceentric disks'. The eccentric strapstare'connected .byro'dsh to the table. The decking or table L is pref- Y erably provided with adiag'onal front edge' asshown in Fig. 2.

It will be understood that if the apparatus i is designed to treat-only one particular class ab e raming b, spring lath supports c lfor of materialv or tio-separate one specific grade of ore it will not be necessary to provide carried 'byeshaft/m1l mounted in suitablev ioo . then thinly dressing it by spraying. andmeans for adjustin either the inclination of the table or to'al ow for variation in the dra link gear and eccentric gear.l i

ing a' stream of Water 'over the delivery end of the belt so ais-to wash the-contents 01T without'materially aii'ecting or dissipating 30 the' oil coating.

' What I claim as my invention and desire to secure by Letters Patent is .,1. In an ore concentrating apparatus, ai values collecting element composed of woven hard duck soaked in an oil, and then thinly ldressed with another oil, one of said oils being a mineral oil andthe other a vegetable drying oil. V

2.. Inl an orcl concentrating apparatus a values collectingI element composedl of woven hard duck the surface of which is made slightly adhesive to the metallic parts 4of the pulp by treating it rst with a drying oil and 'then with a minera-l oil." 3. In `an ore concentrating apparatus a values collecting element composed of woven hard duck soaked in linseed oil and then thinly dressed with mineral oil.
